Is reaction of white copper sulphate with water exothermic or endothermic?
The reaction of white copper sulfate with water is exothermic because it releases heat as it dissolves in water. This heat is generated due to the breaking of bonds between the copper and sulfate ions in the solid compound.
When solid kbr is dissolved in water the solution gets colder is this endothermic or exothermic?
The process of dissolving solid KBr in water and the resulting decrease in temperature is an exothermic reaction. This means that heat is being released to the surroundings during the dissolution process.
When solid sodium hydroxide is added to water the solution gets hot is this endothermic or exothermic?
When solid sodium hydroxide is added to water, the process is exothermic because it releases heat. The heat is generated as the sodium hydroxide dissolves in water, and the surrounding environment experiences a temperature increase.
Is melting of candle an exothermic or endothermic reaction?
The melting of a candle is an endothermic process because heat is required to break the intermolecular forces holding the solid wax together and convert it into a liquid. Energy is absorbed during this phase change.
Is Liquid water turning to ice a endothermic or exothermic process?
The process of freezing is an exothermic process. Particles in a liquid have more energy than those in a solid, hence they vibrate / move more. Therefore, to turn a liquid into a solid, energy needs to be taken out of the liquid. This means energy is given off to its surroundings, making it an exothermic process.
Is solid exothermic or endothermic?
A solid is itself neither endothermic or exothermic. However the phase change from liquid to solid will likely be exothermic.
Is ammonium chloride is an exothermic?
The dissolution of ammonium chloride in water is an endothermic process, meaning it absorbs heat from its surroundings. This is because breaking the ionic bonds in solid ammonium chloride requires energy, resulting in a decrease in temperature.
Is burning gasoline an exothermic process or an endothermic process?
Solid to gas (sublimation) is endothermic (takes in heat).In other words:A phase change from the solid state to the gas state is endothermic.Sublimation is endothermic (takes in energy).Heat energy must be provided to make it work.When there is a change of state from a solid to a liquid, a solid to a gas, or a liquid to a gas, at a constant temperature, the process is endothermic NOT exothermic. It requires energy to break the intermolecular forces that keep the molecules together, and that reduces the temperature - heat is taken in.
Is reaction of white copper sulphate with water exothermic or endothermic?
The reaction of white copper sulfate with water is exothermic because it releases heat as it dissolves in water. This heat is generated due to the breaking of bonds between the copper and sulfate ions in the solid compound.
Why is the dissolution of ammonium chloride an exothermic reaction?
The dissolution of ammonium chloride is an exothermic reaction because it releases energy in the form of heat. When ammonium chloride crystals are dissolved in water, the intermolecular forces between the ions and water molecules are stronger than the forces within the solid crystal lattice, resulting in the release of energy as heat.
When solid kbr is dissolved in water the solution gets colder is this endothermic or exothermic?
The process of dissolving solid KBr in water and the resulting decrease in temperature is an exothermic reaction. This means that heat is being released to the surroundings during the dissolution process.

Is liquid exothermic or endothermic?
Depends, Liquid can be both endothermic and exothermic, for example water, if you freeze water and put it in room temperature it will be endothermic, meaning it will absorb the heat form the room. And if you Boil water and put it in a cold place it will become exothermic because its releasing the heat.
Is the reaction of borax and water endothermic or exothermic?
The dissolution of borax in water is an endothermic process, meaning it absorbs heat from its surroundings. This is because energy is required to break the bonds in the solid borax and allow it to dissolve in water.
Is butter melted in a pan a endothermic or exothermic change?
Melting butter in a pan is an endothermic process. It requires energy input to break the bonds of the solid butter and convert it into a liquid state.
